Question

Find f(-11/5) if f(n) = 5n + 6.. A) -17. B) 5. C) -6

Answer 1

$f(n)=5n+6\\\\f\left(-\dfrac{11}{5}\right)=?\\\\subtitute\ n=-\dfrac{11}{5}\ to\ the\ equation:\\\\f\left(-\dfrac{11}{5}\right)=5\cdot\left(-\dfrac{11}{5}\right)+6=-11+6=-5$

Answer 2

f(-11/5)=5(-11/5)+6
f(-11/5) = -11+6
f(-11/5) = -5 so option B is correct
